Cryofibrinogen-associated glomerulonephritis (CryoFiGN) is rare, and its diagnosis is difficult while treatment is not established. We herein report an elderly woman with CryoFiGN who experienced recurrent purpura and nephritic features that subsequently progressed to nephrotic syndrome and required hemodialysis during the 18-month clinical course. ⋯ The diagnosis of CryoFiGN was based on the clinical presentation, characteristic glomerular deposits, and results of laser microdissection and liquid chromatography-tandem mass spectrometry of the glomeruli. This case highlights the potential utility of corticosteroids as a treatment option for patients with CryoFiGN, even after hemodialysis.

Refractory Peritonitis Related to Peritoneal Dialysis Caused by Enterococcus gallinarum: A Case Report.
A 65-year-old woman with a history of peritoneal dialysis undergoing hemodialysis at our hospital presented with a fever after experiencing gastroenteritis symptoms. She had an implanted peritoneal dialysis catheter for draining chylous ascites. After commencing empirical treatment with meropenem, peritoneal effluent samples revealed an increased white blood cell count, and peritonitis was diagnosed. ⋯ Meropenem was changed to vancomycin based on susceptibility testing but subsequently restarted and thereafter changed to ampicillin following exacerbation of peritonitis. Finally, catheter removal led to complete recovery. E. gallinarum is vancomycin-resistant and a rare cause of peritonitis.

Congenital hemoglobin disorders typically present as hemolytic anemia, but there are also numerous reports of thrombotic complications in these diseases, suggesting an associated hypercoagulative state. In hemoglobin Köln, the most common type of unstable hemoglobinopathy worldwide, there have not been many reports of such thrombotic phenomena. ⋯ His father, who also had hemolytic anemia, presumably hemoglobin Köln, had a history of cerebral infarction. This case suggests that hemoglobin Köln, among other congenital hemoglobin disorders, may be a precipitating factor of thrombotic events.

Objective We retrospectively compared the dose, cost, and safety of vadadustat and daprodustat for the treatment of renal anemia in patients with chronic kidney diseases who were not undergoing dialysis. Methods The primary outcome of this study was the change in dose and cost from the initiation of vadadustat and daprodustat treatment. The secondary outcome was the drug safety. ⋯ Conclusion These results suggest that heterogeneity exists in the drug potency and dosage required for treatment between daprodustat and vadadustat. Serious adverse events [death, cardiovascular disease, end stage renal disease (ESRD), and malignancy] occurred in more than 20% of participants with both HIF-PHIs. Further studies are required to confirm the safety of HIF-PHIs.

A 29-year-old Japanese woman was admitted to our hospital with a fever, cardiogenic shock, and cardiac arrest. Laboratory data indicated multiple organ failure in addition to hemoconcentration, hypoalbuminemia, and myocardial damage. ⋯ However, hypovolemic shock and hypoalbuminemia progressed along with severe anemia, and the patient died 18 hours after admission. The patient was diagnosed with systemic capillary leak syndrome associated with coronavirus disease 2019.
